The files xlam00.dat to xlam09.dat contain data of case wb3 from Hudson (1993) at 10 streamwise positions, where y: height over the surface in [cm] U: mean velocity in the x direction, in [cm/s] V: mean velocity in the y direction, in [cm/s] u': rms fluctuating velocity in the x direction, in [cm/s] v': rms fluctuating velocity in the y direction, in [cm/s] u'v': Reynolds shear stress, in [(cm/s)^2] For other quantities refer to the data files. U_b= 12 cm/s : bulk velocity in the lower channel half Re_h=U_b*h / nu= 3380 : Reynolds number The friction velocity at the wavy wall is u_tau_wa = 1.29 cm/s. The file pressure.dat contains pressure data, calculated from the velocity data by Hudson.
